Discord Bot Slash Command Builder
Build Discord application commands visually — slash, user-context, message-context. All 11 option types (string, integer, user, channel, role, attachment, mentionable, etc.) with choices, autocomplete, min/max, channel filters. Copy the JSON + a curl snippet to register it.
Command
Permission integer. Use the Permissions Calculator on this site to build one. Server admins can still override per-command via Integrations settings.
Options (3/25)
No choices — the option accepts any value the user types.

https://discord.com/api/v10/applications/$APPLICATION_ID/guilds/$GUILD_ID/commandsEvery option Discord application commands support, in one builder
Discord's application command API (slash commands, user right-click, message right-click) takes a precise JSON structure. Get the option types wrong or miss a constraint and registration fails with 50035. The official docs cover every field but don't show how they fit together in a real payload — this builder does. Pick command type (CHAT_INPUT / USER / MESSAGE), add up to 25 options of any type, set min/max/length constraints, pre-set choices, enable autocomplete, filter channel options to specific channel types.
All 11 option types supported: STRING (with min_length, max_length, choices, autocomplete), INTEGER + NUMBER (min_value, max_value, choices, autocomplete), BOOLEAN, USER, CHANNEL (with channel_types filter), ROLE, MENTIONABLE, ATTACHMENT, plus SUB_COMMAND and SUB_COMMAND_GROUP for nested commands. default_member_permissions lets you hide the command from non-admins by default (use the Permissions Calculator on this site to build the integer).
Side panel shows both a Discord-style preview of what your users see in the command picker AND the raw JSON. Switch to the curl tab and you get a ready-to-paste registration snippet — one for global commands (POST /applications/{app_id}/commands, propagates in ~1 hour) and one for guild-scoped commands (POST /applications/{app_id}/guilds/{guild_id}/commands, instant — the best way to iterate during development).
Naming rules are validated live: command + option names must be 1-32 lowercase letters, digits, hyphens, or underscores. Descriptions max 100 chars for CHAT_INPUT commands; USER/MESSAGE context commands have no description (they're triggered via right-click). Subcommands nest up to 2 levels deep (COMMAND → SUB_COMMAND_GROUP → SUB_COMMAND → options). Everything that Discord validates, this builder validates first.
Discord Bot Slash Command Builder — FAQ
How long do global slash commands take to appear?
Globally-registered commands can take up to 1 hour to propagate across Discord's servers. For development, register to a specific guild instead — guild commands appear instantly. Switch to global once the command is finalized.
What's the difference between slash, user, and message commands?
CHAT_INPUT (type 1) = /name command with options, triggered by typing. USER (type 2) = right-click a user → Apps menu → your command (no options, has no description). MESSAGE (type 3) = right-click a message → Apps menu → your command. Context commands pair well with moderation bots (right-click → Report this user).
How do I handle autocomplete in my bot?
Set autocomplete: true on a string/integer/number option. Discord sends your bot an APPLICATION_COMMAND_AUTOCOMPLETE interaction as the user types — respond within 3 seconds with up to 25 choice objects. Your bot dynamically generates suggestions (e.g. matching player names from your DB).
What's default_member_permissions vs channel permission overwrites?
default_member_permissions hides the command from users without those permissions (e.g. set 8/Administrator to hide from regular members). Server admins can override per-command via Server Settings → Integrations → Your Bot. Channel overwrites are not checked by this field — they apply separately when the command runs.
Can I nest subcommands?
Yes — max 2 levels deep. Top-level command → sub_command_group → sub_command → options. Example: /mod user ban, /mod user kick, /mod role add. Each leaf sub_command can have its own options. sub_command_groups can't hold options directly, only more sub_commands.
